Question

A 12V BATTERY IS CONNECTED TO A BULB . THE BATTERY SENDS A CURRENT OF 2.5A THROUGH IT . CALCULATE a) THE POWER DELIVERED TO THE BULB AND b ) THE ENERGY TRANSFERRED TO THE BULB IN 5 MINUTES .

Answer 1

Power = potential difference x current = 12 x 2.5 = 30watt Energy =power x time =30 x 5 x 60 = 9000joule

Answer 2

Answer:

P=VI

=12×2.5

=30 watt

E=P x t

(30x 5 ×60) = 9000 joules

hope u find the answer helpful
